Demister

Abstract

The invention discloses a demister. The demister comprises several parallel demisting assemblies, each demisting assembly comprises a gas rising pipe and an outer cylinder, the outer cylinder is arranged on the outer side of the gas rising pipe and is at the same axis line as the gas rising pipe, the gas rising pipe is fixed on a tower disk, the top portion of the gas rising pipe is provided witha sealing cover plate, the circumference of the gas rising pipe is provided with several rectification channels, the rectification channels are horizontally embedded along a tangent direction of an outer wall of the gas rising pipe, a sidewall I of the rectification channels close to one side of the outer cylinder, the other sidewall II is intersectant to the wall of the gas rising pipe, and the rotation direction of the rectification channels is same; the top of the rectification channel is leveled with the sealing cover plate, and the bottom is intersectant to the wall of the gas rising pipe. The demister can realize separation of liquid drops and gas through rectification, acceleration and surface scraping effect of fluid during a flowing process, The demister has the advantages of simple structure, convenient installation, and difficult fouling, and reduces mist entrainment, and can effectively realize gas-liquid separation.

Description

technical field [0001] The invention relates to a gas-liquid separation device, in particular to a mist eliminator. Background technique [0002] A large amount of SO is produced in the production process of electric power, metallurgy, petrochemical and other industries 2 Harmful substances such as dust and dust have brought serious acid rain hazards and smog weather, and are currently the key air pollutants controlled in our country. At present, the wet desulfurization process is widely used in the field of environmental protection to remove sulfur dioxide and other harmful substances in the flue gas, that is, to spray lye on the flue gas to absorb or adsorb these harmful substances. However, in the wet desulfurization process, the flue gas after desulfurization in the absorption tower contains a large number of fine droplets with a particle size of about 10-60 microns, and sulfuric acid, sulfate, SO 2 etc., will not only pollute the atmospheric environment, but also caus...

AI Technical Summary

Problems solved by technology

In the process of separating the liquid phase from the gas phase in this technology, gas-liquid cross-flow can be realized, so the secondary entrainment effect of the gas relative to the liquid droplets is greatly reduced, but the technical structure is very complicated, the processing difficulty is relatively large, and the corresponding processing and production costs are relatively high.
